Long-term effects of traumatic dental injuries of primary dentition on permanent successors: A retrospective study of 596 teeth.

BACKGROUND/AIMS: Traumatic dental injuries of the primary dentition (TDI-p) have a global prevalence of approximately 11%-47%. They have immediate and long-term effects. Original research analysing the long-term sequelae of TDI-p on permanent dentition (LSP) are few in number. The aim of this study was to explore the correlation between age of TDI-p, type of TDI-p and LSP. MATERIAL AND METHODS: Retrospective analysis of patient data from 2008-2017, reporting with LSP due to TDI-p, was performed. Uniform protocols and complete radiographic-photographic records were analysed. There were 638 LSP reported with 596 teeth having complete records. RESULTS: There were 286 children with 153 males (53.5%) and 133 females (46.5%). Mean age of TDI-p causing LSP was 36.57 ± 11.51 months, with severity increasing in the younger age group. The highest number of LSP was associated with avulsion injuries (218, 36.58%), and the odds ratio of the type of TDI-p affect the severity of LSP was 2.0163. Mean age of reporting was 8.54 ± 2.19 years and was lowest for enamel discolorations. Most LSP were not associated with any associated feature (AF), although impaction was highest among all AF (63, 10.57%). CONCLUSION: Age and type of TDI-p affect LSP, with the former being the stronger determinant of its severity. Mean age of reporting of LSP is dependent upon both type of LSP and AF. LSP due to TDI-p can further be graded in terms of severity.

Dens invagination and root dilaceration in double multilobed mesiodentes in 14-year-old patient with anorexia nervosa.

This paper describes a rare case of erupted double supernumerary teeth with unusual morphology in a 14-year-old patient with an eating disorder. The coexistence of dental morphological anomalies: multilobed mesiodens, multiple dens in dente of different types and root dilaceration have not been previously reported. The paper highlights anatomical and radiological aspects of dental abnormalities and clinical implications of delayed treatment.

Dilaceração radicular: relato de caso clínico / Tooth with root dilaceration: case report

A dilaceração radicular é uma anomalia de forma dentária, geralmente associada a fatores etiológicos traumáticos, na qual há uma mudança de direção da raiz, onde a parte calcificada é deslocada em relação à parte não calcificada, podendo ocorrer em qualquer ponto ao longo do comprimento radicular, dependendo do estágio da formação radicular quando ocorre o trauma, o local e a intensidade. Esta condição acomete cerca de 3% dos dentes permanentes. O tratamento da dilaceração radicular é controverso e o planejamento é essencial. O objetivo deste trabalho é demostrar a importância das imagens radiográficas e tomográficas para o diagnóstico e planejamento do tratamento da dilaceração radicular por meio de um caso clínico.

The root dilaceration is an anomaly of tooth form, usually associated with traumatic etiological factors, in which there is a change in the direction of the root, where the calcified portion is offset from the not calcified part, and may occur at any point along the length root, depending on the stage of root formation occurs when injured, it’s location and intensity. This condition affects about 3% of permanent teeth. Treatment of dilaceration root is controversial and planning is essential. The aim of this work is to demonstrate the importance of radiographic and tomographic images for diagnosis and treatment planning of root tearing through a case report.

Prevalence of root dilaceration in adult patients referred to shiraz dental school (2005-2010).

STATEMENT OF PROBLEM: Dilaceration is defined as a sudden change in the axial inclination of root or between the crown and the root of a tooth. There is no previous study evaluating its prevalence in south of Iran. PURPOSE: This study evaluates the prevalence of root dilaceration on the basis of its location in dental arch in a sample of dental patients referring to Shiraz dental school, Iran. MATERIALS AND METHOD: This retrospective study was performed using full mouth periapical radiographs of 250 patients who were referred to Shiraz dental school. Buccal and lingual dilaceration was determined by its known" bull's eye" appearance in the radiographs or if the deviation was in the mesial or distal directions; the angle of 90 degree or greater between the deviation and the axis of root was the inclusion criteria. RESULTS: Root dilaceration was detected in 0.3% of teeth and 7.2% of patients. It was distributed equally between the maxilla and mandible. Mandibular second molar was the most frequent dilacerated tooth (1.6%) followed by maxillary first molar (1.3%) and mandibular first molar (0.6%). The alveolar nerve was the most common anatomic structure near dilacerated teeth. CONCLUSION: According to this study, root dilaceration is an uncommon developmental anomaly which occurs mostly in the posterior teeth.

Endo-esthetic Management of Permanent Maxillary Lateral Incisor with Severe Root Dilaceration in a 12-year-old Child.

Functional, esthetic and endodontic restoration of a pulpally involved permanent incisor with root dilaceration often presents a daunting clinical challenge. The outcome of conventional treatment modalities like surgical removal of the tooth followed by orthodontic closure of the space is time consuming and esthetically compromising. Even the prosthetic and implantalogical rehabilitation after extraction is not possible until the patient reaches certain age; while the compliance is a problem with the use of removable partial denture in young children. Autoalloplastic anterior tooth transplantation can lead to physical and psychological trauma in a young individual. Thus endo-esthetic management of such teeth helps in maintaining both morphology and esthetics in a growing child until the permanent long lasting prosthetic solution is sought after the complete development of the dentition and jaws. This treatment option for a pulpally involved permanent incisor with root dilaceration involves completing the endodontic treatment in a partially calcified and aberrantly located root canal followed by the use of light transmitting fiber post and core build up using composite resin.
